| Abstract: | Pre-splitting blasting technology was adopted in Jingfu expressway cut excavation blasting. According to the natural conditions ,the parameters of pre-splitting blasting was calculated and ascertained by using pre-splitting slot crack mechanism. The project schedule was speeded up, the quality of project was improved and a better economic efficiency was achieved. |
